Below in conjunction with the drawings and specific embodiments, the present invention is described further.

As shown in Figure 1, the single door that the present embodiment provides comprises a body 10, and the side of this body 10 is vertically provided with vertical rod 20, preferably vertical rod 20 is arranged and is on the doorframe that a body 10 is corresponding.The top of this body 10 has also been horizontally disposed with slide rail 30, and the upper end of door body 10 is fixedly connected with the slide bar 40 vertically placed, and one end that slide bar 40 is not connected with door body 10 is arranged on slide rail 30, and can slide on the length direction of slide rail 30.

The junction of vertical rod 20 and slide rail 30 is provided with automatic door control mechanism 50, as shown in Figures 2 and 3, automatic door control mechanism 50 comprises control module (not shown), motor 51, the shaft coupling 52 be connected with the output shaft of motor 51, the worm screw 53 be connected with shaft coupling 52, the worm gear 54 coordinated with worm screw 53, the drive link 56 being arranged on the electromagnetic brake 55 on worm gear 54 and opening for driving gate body 10 or close, the power intake of electromagnetic brake 55 is fixedly connected with worm gear 54, clutch end is fixedly connected with one end of drive link 56, the other end of drive link 56 is movably connected on a body 10 by oscillating bearing 57.The work schedule of motor 51 and electromagnetic brake 55 is controlled by control module.

The control module that the control module that the present embodiment uses is commonly used for automatic door field, with the peripheral auxiliary equipment of routine as the devices such as enabling signal source apparatus, gate control system, safety device or centralized control system or system are used in conjunction with each other, and work can be carried out according to corresponding signal control motor 51 and/or electromagnetic brake 55.Stationarity when working in order to ensure automatic door control mechanism 50, motor 51 preferably uses DC brushless motor.

Electromagnetic brake 55 comprises the clutch plate 55a being positioned at its power intake and the keep plate 55b being positioned at its clutch end, when electromagnetic brake 55 is energized clutch plate 55a bonded to each other with keep plate 55b together with, door body 10 and motor 51 are in transmission connection, single door is in automatic control mode, and the opening and closing of single door are driven by motor; When electromagnetic brake 55 power-off, clutch plate 55a and keep plate 55b is separated from each other, and single door is in MANUAL CONTROL mode, and the opening and closing of single door promote a body 10 by user and drive.The object of such setting is when making to have a power failure, and the single door of the present embodiment by cut-outs that be in transmission connection of door body 10 and motor 51, can discharge the load of motor 51, allow single door be switched to MANUAL CONTROL mode automatically.

For the ease of the operation of single door under MANUAL CONTROL mode, the present embodiment is also provided with handle 11 on the door body 10 of single door, and handle 11 can be conventional handle, no longer describes in detail herein.

The electromagnetic brake 55 used in the present embodiment can be conventional electromagnetic brake.Consider that clutch plate 55a and the keep plate 55b of electromagnetic brake 55 may produce large stroke in the process of laminating fast, affect the stationarity of single door work, the electromagnetic brake 55 that the present embodiment uses is optimized in the electromagnetic brake structure of routine, concrete optimal way is, the keep plate 55b of electromagnetic brake 55 offers spring eye 55c, spring eye 55c is blind hole, in order to process this spring eye 55c on the basis not destroying electromagnetic brake 55 original structure, directly can offer through hole on keep plate 55b, then screw or plug is used to be blocked by this through hole, form blind hole, i.e. spring eye 55c.Be provided with Compress Spring 55d in spring eye 55c, one end of Compress Spring 55d is supported in the bottom of spring eye 55c, and the other end stretches out from the oral area of spring eye 55c, towards the direction of clutch plate 55a.Like this, when electromagnetic brake 55 is energized, Compress Spring 55d is compressed, clutch plate 55a and keep plate 55b can be relaxed may produce large stroke in the process of laminating fast, when electromagnetic brake 55 power-off, clutch plate 55a and keep plate 55b can quick separating under the effect of Compress Spring 55d, improves the sensitivity of electromagnetic brake 55.

In the present embodiment, vertical rod 20 is also provided with a follower link 60, follower link 60 is the rod member identical with drive link 56, one end of follower link 60 is rotatably connected in vertical rod 20, the other end is also movably connected on a body 10 by oscillating bearing 61, and the heavy burden of such door body 10 can be dispersed between drive link 56 and follower link 60.Certainly, those skilled in the art also can arrange the follower link 60 of more than as required in vertical rod 20.

In order to improve stationarity during single door work further, the door body 10 of the single door of the present embodiment runs according to specific rate curve and accelerating curve in closure or openness process.For door body 10 opening process: suppose that door body 10 needs used time T from being closed into open completely completely ₁+ T ₂second, this time can be determined according to actual needs; Be set in 0 ~ T ₁inside door body 10 accelerated motion second, time initial, the speed of door body 10 and acceleration are all zero; At T ₁~ T ₂second inside door body 10 uniform motion, the acceleration of this stage door body 10 is zero, supposes that the movement velocity of this stage door body 10 is M simultaneously; At T ₂~ (T ₁+ T ₂) inside door body 10 retarded motion second, at T ₁+ T ₂second time the speed of door body 10 and acceleration be all zero, thus can by mathematical computations obtain door body 10 from be closed into the velocity expression opened completely completely and acceleration expression formula as follows:

$V=\left\{\begin{array}{cc}\frac{M}{2}\sin [\frac{\mathrm{\&pi;}}{T_1}x-\frac{\mathrm{\&pi;}}{2}]+\frac{M}{2}& (0\&le;x<T_1)\\ M& (T_1\&le;x\&le;T_2)\\ -\frac{M}{2}\sin [\frac{\mathrm{\&pi;}}{T_1}(x-T_2)-\frac{\mathrm{\&pi;}}{2}]+\frac{M}{2}& (T_2\&le;x\&le;T_1+T_2)\end{array}\right.$
